This is the timelapser tool I spoke of yesterday. I was having trouble hosting it since it contains a .exe file, which google drive did not like. It is now on itch.io, you can find it here:

This is what the window looks like. Beware that it will produce a windows defender suspicion since it can write files, but it is basically just a frontend gui that executes python files via a command line. You can see the code it runs in the python files packaged with it if you are worried. In order to remove this you have to pay microsoft money for a signed exe or maybe there is another way I haven't found. If you don't want to worry about it you don't need it to play the game it is just if you want to make your own timelapses of your past games. It will render it to .mp4 and you can do whatever with it.
Here is an example of its output. Report bugs on the discord
